BACKGROUND

Field of the Invention

This invention relates generally to door lock devices, and more particularly to intelligent door lock systems that are retrofitted to existing door lock devices.

Brief Description of the Related Art

Door lock assemblies often include deadbolts. Typically such an assembly included a latch which is depressed during closure of the door and, with substantially complete closure, extends into a recess of the door strike. Such a latch by itself is often easy to improperly depress-release by an unauthorized person, with a card-type element or even a pry bar. Also the outer knob assembly can be torqued off with a wrench to gain access to the mechanism and thereby to the room closed by the door. Deadbolts are not as susceptible to these unauthorized activities. Doors having deadbolts typically use a latch mechanism. This is because (1) the latch holds the door snug against rattling whereas the deadbolt by necessity must have clearance between it and the strike plate recess edges (but because of the clearance, the door can rattle), and (2) the latch automatically holds the door shut since it is only momentarily depressed during door closure from its normally extended condition and then extends into a door strike recess when the door is fully closed.

Except in rare devices where the deadbolt is operated by an electrical solenoid, the deadbolt, to be effective, must be manually thrown by a person inside the room or building, or if the deadbolt is actuatable by an external key, the person leaving the room or building must purposely engage the deadbolt by a key as the person leaves. However, if a person forgets to so actuate the deadbolt, either manually with an inner hand turn when inside, or by a key outside, an intruder need only inactivate the latch mechanism in order to gain unauthorized entry. Motel and hotel rooms often do not even have a key actuated deadbolt and thus are particularly susceptible to unauthorized entry and theft when the person is not in the room.

In recent years, mechanisms were developed to enable retraction, i.e. Inactivation, of the deadbolt simultaneously with the latch for quick release even under panic exit conditions. But to lock the door still required manual actuation of the deadbolt with the inner hand turn or a key on the outside.

In one door lock assembly a deadbolt is shift able between an extended lock position and a retracted position and means for shifting the deadbolt from the extended position to the retracted position which is characterized by biasing means for applying a bias on the deadbolt toward the extended lock position; restraining means for restraining the deadbolt in the retracted position against the bias of the biasing means and being actuatable to release the deadbolt to enable the biasing means to shift the deadbolt to the extended lock position; and trigger means. For actuating the restraining means to release the deadbolt and thereby allow the biasing means to shift the deadbolt to the extended lock position.

Such a door lock assembly is for use in a door frame and thus the invention extends to the door lock assembly of the present invention in cooperation with a door frame.

Some deadbolt locks are automatically actuated with closure of the door, the deadbolt being mechanically actuated to the extended lock position. The deadbolt in its retracted position is spring-biased toward the extended lock position, but is retained in a cocked condition by a deadbolt restraining and releasing device which is trigger actuatable to activate the deadbolt into its locked condition. The trigger mechanism may have a portion that protrudes from the door to engage the door strike of the door frame upon closure of the door, thereby causing the deadbolt to be released and shifted to the locked condition. The protruding portion of the trigger mechanism can also serve to hold the door snug against rattling.

In another door lock assembly for a hinged door and cooperative with a door strike of a door frame, a deadbolt is provided mounting in the door. The dead bolt is shift able between a retracted non-lock position and an extended lock position. It includes a manually operable device for shifting the deadbolt from the extended lock position to the retracted non-lock position. A biasing device applies a bias on the deadbolt toward the extended lock position. A restraining device is biased into a restraining relationship with the deadbolt in the retracted position. This restrains the deadbolt in the retracted position against the bias of the biasing device. A trigger releases a restraining means when the trigger is actuated and includes a protruding portion for engaging a door strike for actuating the trigger. A door strike includes a surface to engage and depress the trigger protruding portion for actuation of the trigger and release of the deadbolt restraining means, and includes an opening to receive the deadbolt when extended.

The use of electronic systems for the control and operation of locks is becoming increasingly common. The present invention is directed to an arrangement that permits the electronic and manual control of the lock operation to be separated to allow manual operation of the lock independently of the electronic drive system for the lock. The lock of the present invention is useful in situations where an electronic controller is temporarily unavailable, for example where a controller has been lost, misplaced or damaged.

There are currently some electronic deadbolt lock arrangements. In one device, a lock has a bolt movable between locked and unlocked conditions. The lock has a manual control device that serves to operate the lock between locked and unlocked conditions. A power drive is coupled by a transmission to the manual control device. The lock is operated between the locked and unlocked conditions in response to operation of the power drive. A transmission mechanism couples the manual control device and the power drive, whereby the lock moves between the locked and unlocked conditions. The transmission mechanism is operable to decouple the power drive from the manual control means to enable the lock to be operated by the manual control device independently of the power drive.

However, most deadbolts require that a user manually use a metal key to lock or unlock the deadbolt. There is a need to provide a deadbolt that can be retrofitted to an existing door. There is further need for a deadbolt that can be locked or unlocked electronically, automatically, and remotely. There is a need for an intelligent door lock system where a position of a drive shaft, coupled to a dead bold, is used to detect if the dead bold, lock, is locked, unlocked, a depth of the dead bold travel and the like. There is a further need for an intelligent door lock system where the drive shaft is repositioned in an absolute state. There is a further need for an intelligent door lock system where the a positioning sensing device is positioned on a drive shaft, or an element coupled to the drive shaft, and a rotation of the drive shaft, along a Z axis, provides information relative as to whether someone has used a key, the ring, lock picking and the like.

It is used to manage and secure access to network services, data, provides access, communicates with door systems to open and close doors and the like.

As used herein, the term “computer” or “mobile device or computing device” is a general purpose device that can be programmed to carry out a finite set of arithmetic or logical operations. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem. A computer can include of at least one processing element, typically a central processing unit (CPU) and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit that can change the order of operations based on stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.

As used herein, the term “Internet” is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support email. The communications infrastructure of the Internet consists of its hardware components and a system of software layers that control various aspects of the architecture, and can also include a mobile device network, e.g., a cellular network.

As used herein, the term “extranet” is a computer network that allows controlled access from the outside. An extranet can be an extension of an organization's intranet that is extended to users outside the organization that can be partners, vendors, and suppliers, in isolation from all other Internet users. An extranet can be an intranet mapped onto the public Internet or some other transmission system not accessible to the general public, but managed by more than one company's administrator(s). Examples of extranet-style networks include but are not limited to:

-   -   LANs or WANs belonging to multiple organizations and         interconnected and accessed using remote dial-up     -   LANs or WANs belonging to multiple organizations and         interconnected and accessed using dedicated lines     -   Virtual private network (VPN) that is comprised of LANs or WANs         belonging to multiple organizations, and that extends usage to         remote users using special “tunneling” software that creates a         secure, usually encrypted network connection over public lines,         sometimes via an ISP

As used herein, the term “Intranet” is a network that is owned by a single organization that controls its security policies and network management. Examples of intranets include but are not limited to:

-   -   A LAN     -   A Wide-area network (WAN) that is comprised of a LAN that         extends usage to remote employees with dial-up access     -   A WAN that is comprised of interconnected LANs using dedicated         communication lines     -   A Virtual private network (VPN) that is comprised of a LAN or         WAN that extends usage to remote employees or networks using         special “tunneling” software that creates a secure, usually         encrypted connection over public lines, sometimes via an         Internet Service Provider (ISP)

For purposes of the present invention, the Internet, extranets and intranets collectively are referred to as (“Network Systems”).

As used herein, “Haptic Feedback”, “Haptic technology”, or “Haptics”, is a visual, audio or tactile feedback and visual technology, which takes advantage of the sense of an event, by touch, visual or audio. Haptic feedback can be by applying forces, vibrations, visual and audio feedback or motions to the user. This mechanical stimulation can be used to assist in the creation of virtual objects in a computer simulation, to control such virtual objects, and to enhance the remote control of machines and devices (telerobotics). It has been described as doing for the sense of touch what computer graphics does for vision. Haptic devices can incorporate tactile sensors that measure forces exerted by the user on the interface. When referring to mobile phones and similar devices, this generally means the use of vibrations from the device's vibration alarm to denote that a touchscreen button has been pressed. In this particular example, the phone would vibrate slightly in response to the user's activation of an on-screen control, making up for the lack of a normal tactile response that the user would experience when pressing a physical button. Haptic feedback can provide a visual indication of an event.

Referring now to FIG. 1(a), one embodiment of an intelligent door lock system 10 is illustrated, as more fully described hereafter.

In one embodiment, the intelligent door lock system 10 is configured to be coupled to a structure door 12, including but not limited to a house, building and the like, window, locked cabinet, storage box, bike, automobile door or window, computer locks, vehicle doors or windows, vehicle storage compartments, and the like. In one embodiment, the intelligent door lock system 10 is coupled to an existing drive shaft 14 of a lock device 22 already installed and is retrofitted to all or a portion of the lock device 22, which includes a bolt/lock 24. In another embodiment, the intelligent door lock system 10 is attached to a door 12, and the like, that does not have a pre-existing lock device. FIG. 1(b) illustrates door lock elements that can be at an existing door, to provide for the mounting of the intelligent door lock system 10 with an existing lock device 22.

FIG. 1(b) illustrates one embodiment of a lock device 22 that can be pre-existing at a door 10 with the intelligent door lock system 10 retrofitted to it. Components of the lock device 22 may be included with the intelligent door lock device 10, as more fully discussed hereafter.

In one embodiment, the intelligent door lock system 10 includes a positioning sensing device 16, a motor 38, an engine/processor 36 with a memory and one or more wireless communication devices 40 coupled to a circuit 18. The motor 38 converts any form of energy into mechanical energy. As a non-limiting example, three more four wireless communications devices 40 are in communication with circuit 18.

In one embodiment, the intelligent door lock system 10 is provided with the position sensing device 16 configured to be coupled to the drive shaft 14 of the lock device 22. The position sensing device 16 senses position of the drive shaft 14 and assists in locking and unlocking the bolt/lock 24 of the lock device 22. The engine 36 is provided with a memory. The engine 36 is coupled to the positioning sensing device 16. A circuit 18 is coupled to the engine 36 and an energy source 50 is coupled to the circuit. A device 38 converts energy into mechanical energy and is coupled to the circuit 18, positioning sensing device 16 and the drive shaft 14. Device 38 is coupled to the energy source 50 to receive energy from the energy source 50, which can be via the circuit 18.

In one embodiment, the intelligent door lock system 10 includes any or all of the following, a face plate 20, ring 32, latches such as wing latches 37, adapters 28 coupled to a drive shaft 14, one or more mounting plates 26, a back plate 30, a power sensing device 46, energy sources, including but not limited to batteries 50, and the like.

In one embodiment (see FIG. 1(c)), the intelligent door lock system 10 retrofits to an existing lock device 22 already installed and in place at a door 12, and the like. The existing lock device 12 can include one or more of the following elements, drive shaft 14, a lock device 22 with the bolt/lock 24, a mounting plate 26, one or more adapters 28 for different lock devices 22, a back plate 30, a plurality of motion transfer devices 34, including but not limited to, gears 34, and the like.

In one embodiment, the memory of engine/processor 36 includes states of the door 12. The states are whether the door 12 is a left handed mounted door, or a right handed mounted door, e.g., opens from a left side or a right side relative to a door frame. The states are used with the position sensing device 16 to determine via the engine/processor 36 if the lock device 22 is locked or unlocked.

In one embodiment, the engine/processor 36 with the circuit 18 regulates the amount of energy that is provided from energy source 50 to the motor 38. This thermally protects the motor 38 from receiving too much energy and ensures that the motor 38 does not overheat or become taxed.

FIG. 1(d) illustrates various embodiments of the positioning sensing device 16 coupled to the drive shaft 14.

A variety of position sensing devices 16 can be used, including but not limited to, accelerometers, optical encoders, magnetic encoders, mechanical encoders, Hall Effect sensors, potentiometers, contacts with ticks, optical camera encoders, and the like.

As a non-limiting example, an accelerometer 16, well known to those skilled in the art, detects acceleration. The accelerometer 16 provides a voltage output that is proportional to a detected acceleration. Suitable accelerometers 16 are disclosed in, U.S. Pat. No. 8,347,720, U.S. Pat. No. 8,544,326, U.S. Pat. No. 8,542,189, U.S. Pat. No. 8,522,596. EP0486657B1. EP 2428774 A1, incorporated herein by reference.

In one embodiment, the position sensing device 16 is an accelerometer 16. Accelerometer 16 includes a flex circuit coupled to the accelerometer 16. The accelerometer reports X, Y, and X axis information to the engine/processor 36 of the drive shaft 14. The engine/processor 36 determines the orientation of the drive shaft 14, as well as door knocking, bolt/lock 24 position, door 12 close/open (action) sensing, manual key sensing, and the like, as more fully explained hereafter.

Suitable optical encoders are disclosed in U.S. Pat. No. 8,525,102, U.S. Pat. No. 8,351,789, and U.S. Pat. No. 8,476,577, incorporated herein by reference.

Suitable magnetic encoders are disclosed in U.S. Publication 20130063138, U.S. Pat. No. 8,405,387, EP2579002A1, EP2642252 A1, incorporated herein by reference.

Suitable mechanical encoders are disclosed in, U.S. Pat. No. 5,695,048, and EP2564165A2, incorporated herein by reference.

Suitable Hall Effect sensors are disclosed in, EP2454558B1 and EP0907068A1, incorporated herein by reference.

Suitable potentiometers are disclosed in, U.S. Pat. No. 2,680,177, EP1404021A3, CA2676196A1, incorporated herein by reference.

In various embodiments, the positioning sensing device 16 is coupled to the drive shaft 14 by a variety of means, including but not limited to the adapters 28. In one embodiment, the position sensing device 16 uses a single measurement, as defined herein, of drive shaft 14 position sensing which is used to determine movement in order the determine the location of the drive shaft 14 and the positioning sensing device 16. The exact position of the drive shaft 14 can be measured with another measurement without knowledge of any previous state. Single movement, which is one determination of position sensing, is the knowledge of whether the door 12 is locked, unlocked or in between. One advantage of the accelerator is that one can determine position, leave if off, come back at a later time, and the accelerometer 16 will know its current position even if it has been moved since it has been turned off. It will always know its current position.

In one embodiment, the positioning sensing device 16 is directly coupled to the drive shaft 14, as illustrated in FIG. 1(d). Sensing position of the positioning sensing device 16 is tied to the movement of the drive shaft 14. In one embodiment with an accelerometer 16, the accelerometer 16 can detect X, Y and Z movements. Additional information is then obtained from the X, Y, and Z movements. In the X and Y axis, the position of the drive shaft 14 is determined; this is true even if the drive shaft 14 is in motion. The Z axis is used to detect a variety of things, including but not limited to, door 12 knocking, picking of the lock, break-in and unauthorized entry, door 12 open and closing motion. If a mobile device 201 is used to open or close, the processor 36 determines the lock state.

In one embodiment, the same positioning sensing device 16 is able to detect knocks by detecting motion of the door 12 in the Z axis. As a non-limiting example, position sensing is in the range of counter and dock wise rotation of up to 180 degrees for readings. The maximum rotation limit is limited by the position sensing device 16, and more particularly to the accelerometer cable. In one embodiment, the result is sub 1° resolution in position sensing. This provides a higher lifetime because sampling can be done at a slower rate, due to knowing the position after the position sensing device 16 has been turned off for a time period of no great 100 milli seconds. With the present invention, accuracy can be enhanced taking repeated measurements. With the present invention, the positioning sensing device 16, such as the accelerometer, does not need to consume additional power beyond what the knock sensing application already uses.

In one embodiment, the position sensing device 16 is positioned on the drive shaft 14, or on an element coupled to the drive shaft 14. In one embodiment, a position of the drive shaft 14 and power sensing device and/or a torque limited link 38 are known. When the position of the drive shaft 14 is known, it is used to detect if the bolt/lock 24 of a door lock device 22 is in a locked or unlocked position, as well as a depth of bolt/lock 24 travel of lock device 22, and the like. This includes but is not limited to if someone, who turned the bolt/lock 24 of lock device 22 from the inside using the ring 32, used the key to open the door 12, if the door 12 has been kicked down, attempts to pick the bolt/lock 24, bangs on the door 12, knocks on the door 12, opening and closing motions of the door 12 and the like. In various embodiments, the intelligent door lock system 10 can be interrogated via hardware, including but not limited to a key, a mobile device, a computer, key fob, key cards, personal fitness devices, such as Fitbit®, nike fuel, jawbone up, pedometers, smart watches, smart jewelry, car keys, smart glasses, including but not limited to Google Glass, and the like.

During a power up mode, the current position of the drive shaft 14 is known.

Real time position information of the drive shaft 14 is determined and the bolt/lock 24 of lock device 22 travels can be inferred from the position information of the drive shaft 14. The X axis is a direction along a width of the door 12, the Y axis is in a direction along a length of a door 12, and the Z axis is in a direction extending from a surface of the door 12.

In one embodiment, the accelerometer 16 is the knock sensor. Knocking can be sensed, as well as the number of times a door 12 is closed or opened, the physical swing of the door 12, and the motion the door 12 opening and closing. With the present invention, a determination is made as to whether or not someone successfully swung the door 12, if the door 12 was slammed, and the like. Additionally, by coupling the position sensing device 16 on the moveable drive shaft 14, or coupled to it, a variety of information is provided, including but not limited to, if the bolt/lock 24 is stored in the correct orientation, is the door 12 properly mounted and the like.

In one embodiment, a calibration step is performed to determine the amount of drive shaft 14 rotations to fully lock and unlock the bolt/lock 24 of lock device 22. The drive shaft 14 is rotated in a counter-counter direction until it can no longer rotate, and the same is then done in the clock-wise direction. These positions are then stored in the engine memory. Optionally, the force is also stored. A command is then received to rotate the drive shaft 14 to record the amount of rotation. This determines the correct amount of drive shaft 14 rotations to properly lock and unlock the lock device 22.

In another embodiment, the drive shaft 14 is rotated until it does not move anymore. This amount of rotation is then stored in the memory and used for locking and unlocking the lock device 22.

In another embodiment, the drive shaft 14 is rotated until it does not move anymore. However, this may not provide the answer as to full lock and unlock. It can provide information as to partial lock and unlock. Records from the memory are then consulted to see how the drive shaft 14 behaved in the past. At different intervals, the drive shaft 14 is rotated until it does not move anymore. This is then statistically analyzed to determine the amount of drive shaft 14 rotation for full locking and unlocking. This is then stored in the memory.

The back-end 68 knows that an intelligent door lock system 10 is with a user, and includes a database with the user's account information. The back-end 68 knows if the user is registered or not. When the intelligent door lock system 10 is powered up, the back-end 68 associated that intelligent door lock system 10 with the user.

The conditioning electronics 80 can provide signal conditioning, including but not limited to amplification, filtering, converting, range matching, isolation and any other processes required to make sensor output suitable for processing after conditioning. The conditioning electronics can provide for, DC voltage and current, AC voltage and current, frequency and electric charge.

In one embodiment, electronics 92 are provided for use in intelligent door system 10 analysis of data transmitted via System Networks. The electronics 92 can include an evaluation device 94 that provides for comparisons with previously stored intelligent door system 10 information.

Signal filtering is used when the entire signal frequency spectrum contains valid data. Filtering is the most common signal conditioning function, as usually not all the signal frequency spectrum contains valid data.

Signal amplification performs two important functions: increases the resolution of the inputted signal, and increases its signal-to-noise ratio.

Suitable amplifiers 86 include but are not limited to sample and hold amplifiers, peak detectors, log amplifiers, antilog amplifiers, instrumentation amplifiers, programmable gain amplifiers and the like.

Signal isolation can be used in order to pass the signal from to a measurement device without a physical connection. It can be used to isolate possible sources of signal perturbations.

In one embodiment, the intelligent door lock system back-end 68 can provide magnetic or optic isolation. Magnetic isolation transforms the signal from voltage to a magnetic field, allowing the signal to be transmitted without a physical connection (for example, using a transformer). Optic isolation takes an electronic signal and modulates it to a signal coded by light transmission (optical encoding), which is then used for input for the next stage of processing.

In one embodiment, the intelligent door lock system 10 and/or the intelligent door lock system back-end 68 can include Artificial Intelligence (AI) or Machine Learning-grade algorithms for analysis. Examples of AI algorithms include Classifiers, Expert systems, case based reasoning, Bayesian networks, and Behavior based AI, Neural networks, Fuzzy systems, Evolutionary computation, and hybrid intelligent systems.

Information received or transmitted from the back-end 68 to the intelligent door system 10 and mobile device 210 can use logic resources, such as AI and machine learning grade algorithms to provide reasoning, knowledge, planning, learning communication, and create actions.

In one embodiment, AI is used to process information from the intelligent door lock system 10, from mobile device 210, and the like. The back-end 68 can compute scores associated with various risk variables involving the intelligent door lock system 10. These score can be compared to a minimum threshold from a database and an output created. Alerts can be provided to the intelligent door lock system 10, mobile device 210 and the like. The alert can provide a variety of options for the intelligent door lock system 10 to take, categorizations of the received data from the mobile device 210, the intelligent door lock system 10, and the like, can be created. A primary option can be created as well as secondary options.

In one embodiment, data associated with the intelligent door lock system 10 is received. The data can then be pre-processed and an array of action options can be identified. Scores can be computed for the options. The scores can then be compared to a minimum threshold and to each other. A sorted list of the action options based on the comparison can be outputted to the intelligent door lock system 10, the mobile device 210 and the like. Selections can then be received indicating which options to pursue. Action can then be taken. If an update to the initial data is received, the back-end 68 can then return to the step of receiving data.

Urgent indicators can be determined and directed to the intelligent door lock system 10, including unlocking, locking and the like.

Data received by the intelligent door lock system 10 and mobile device 210 can also be compared to third party data sources.

In data evaluation and decision making, algorithm files from a memory can be accessed specific to data and parameters received from the intelligent door lock system 10 and mobile device 210.

Scoring algorithms, protocols and routines can be run for the various received data and options. Resultant scores can then be normalized and weights assigned with likely outcomes.

The intelligent door lock system 10 can be a new lock system mounted to a door 12, with all or most of the elements listed above, or it can be retrofitted over an existing lock device 22.

To retrofit the intelligent door lock system 10 with an existing lock system, the user makes sure that the existing lock device 22 and bolt/lock 24 is installed right-side up. The existing thumb-turn is then removed. With some lock devices 22, additional mounting plates 26 need to be removed and the intelligent door lock system 10 can include replacement screws 56 that are used. The correct mounting plate 26 is then selected. With the existing screws 56 in the thumb-turn, the user sequentially aligns with 1 of 4 mounting plates 26 that are supplied or exist. This assists in determining the correct diameter and replace of the screws 56 required by the bolt/lock 24. The mounting plate 26 is then positioned. The correct adapter 28 is positioned in a center of the mounting plate 26 to assist in proper positioning. Caution is made to ensure that the adapter 28 does not rub the sides of the mounting plate 26 and the screws 56 are then tightened on the mounting plate 26. The intelligent door lock system bolt/lock 24 of lock device 22 is then attached. In one embodiment, this is achieved by pulling out side wing latches 36, sliding the lock device 22 and/or bolt/lock 24 over the adapter 28 and pin and then clamping down the wings 36 to the mounting plate 26. The faceplate is rotated to open the battery compartment and the battery tabs are then removed to allow use of the battery contacts 64. An outer metal ring 32 to lock and unlock the door 12 is then rotated. An app from mobile device 210 and/or key then brings the user through a pairing process.

A door 12 can be deformed, warped, and the like. It is desirable to provide a customer or user, information about the door, e.g., if it is deformed, out of alignment, if too much friction is applied when opening and closing, and the like.

As recited above, the current sensor 46 monitors the amount of current that goes to the motor 38 and this information is received and processed by the engine/processor 36 with memory and is coupled to the circuit 18. The amount of current going to the motor 38 is used to determine the amount of friction experienced by door 12 and/or lock device 22 in opening and/or closing, as applied by the intelligent door lock system 10 and the positioning sensing device 16 to the drive shaft 14. The circuit 18 and engine/processor 36 can provide for an adjustment of current. The engine/processor 36 can provide information regarding the door and friction to the user of the door 12.

In one embodiment of the present invention, the intelligent door lock system 10 provides an ability to sense friction on the lock device 22 and/or door 12 by measuring the torque required to move the bolt/lock 24. The intelligent door lock system 10 increases the applied torque gradually until the bolt/lock 24 moves into its desired position, and the applied torque is the minimum amount of torque required to move the bolt/lock 24, which is directly related to how deformed the door is.

In one embodiment, when a bad door is detected, a customer can be notified that their door may require some servicing. In one embodiment, door deformation can be detected with a torque device is used to determine if the torque applied when the door is rotated is too high. As a non-limiting example, this can be 2-15 in lbs of torque The intelligent door lock system back end 68 can then perform a comparison between the measured torque with a standard, or a norm that is included in the one or more databases 88.

In one embodiment of the present invention, before the door is serviced, the intelligent door lock system 10 allows operation by offering a high-friction mode. As a non-limiting example, the high friction mode is when, as non-limiting examples, 2 inch lbs, 3 inch lbs., 3.5 inch pounds, and the like are required to open the door. In the high friction mode, the bolt/lock 24 is driven while the user is pushing, lifting, torquing the door, pulling, performing visual inspections of rust, blockage, other conditions that can compromise a door and the like, that is applied to the doorknob. The position sensing device 16 is used to determine if the bolt/lock 24 was moved to a final position. In the high friction mode, motion of the door closing is confirmed. Upon detecting the closing of the door, the bolt/lock 24 is then driven. When the user receives an auditory, visual, or any other type of perceptible confirmation, the user then knows that the door has been locked. In one embodiment, the firmware elements, of the intelligent door lock system 10, as well as other door lock device 22 elements, can also attempt to drive the bolt/lock 24 for a second time when the first time fails. However, this can result in more power consumption, reducing lifetime of the power source, particularly when it is battery 50 based.

In one embodiment of the present invention, the intelligent door lock system 10 seeks to have the motor 38 operate with reduced energy consumption for energy source lifetime purposes, as well as eliminate or reduce undesirable noises, operations, and user experiences that occur when this is a failure in door locking and unlocking, particularly due to door deformation, door non-alignment, as well as other problems with the door that can be irritating to the person locking or unlocking the door.

In one embodiment of the present invention, the intelligent door lock system back-end 68 can track performance of doors and friction levels across time and build a service to encourage users to better maintain their doors. Such service can be a comparison of a door's friction level to other users that are similar geographic locations, at similar weather pattern, such that the user is encouraged to maintain their doors at a competent level. There can be a comparison to standards that at a certain level the door becomes unsafe. Guidelines are provided as to how to maintain their doors. This can be achieved by asking a door user what improves their door, including but not limited to, pushing, lifting, torquing the door, pulling, visual inspections of rust, blockage, other conditions that can compromise a door, and the like. The analysis and comparison can be conducted at the back-end 68 and the results computed to door lock operator as well as others.

In one embodiment of the present invention, the intelligent door lock system 10 has a deformed operation mode that can be activated after a selected amount of time. As a non-limiting example, this can immediately after the user has been notified, more than 1 pico second, 1 second, 5 seconds, and greater periods of time. The deformed operation mode can be activated by the intelligent door lock system 10 itself, or by the intelligent door lock system back-end 68. It can be activated on the door operator's request. In one embodiment, the back-end 68 can anticipate these problems. As non-limiting examples, these can include but are not limited to, due to analysis of doors 12 in similar geographic areas, doors under similar conditions, doors with similar histories, similar environmental conditions, as well as the history of a particular door, and the like.

The deformed mode provides cooperation with the door user to more readily open the door. In one embodiment, this is a mechanism for the door to communicate back to the door lock operator. As a non-limiting example, feedback can be provided to the door operator. Such feedback can include, but is not limited to, communication via, tactile, audio, visual, temperature, electronic, wirelessly, through a computer, mobile device and the like. In another embodiment, the operator can signify to the door the operator's desire to leave by unlocking and opening the door 12. This is a door operator and lock communication. The door operator can close the door, which is sensed by the intelligent door lock system 10, a timer can then be initiated to provide with door operator with a selected time period in which the door operator can manually alleviate the friction problem. When the time has expired, the intelligent door system 10 can then lock the door 12. Upon detecting a successful door locking event, the intelligent door lock system 10 can advise the door operator that there is a successful door locking. If the door locking is not successful, the intelligent door lock system 10 can provide a message to the door operator via a variety of means, including but not limited to a message or alert to the door lock operator's mobile device. Such a mobile device message provides the door operator with notification that door locking was not successful or achieved, and the door lock operator can then take action to lock the door 12 either in person, wirelessly, and the like.

For entry, communication with the lock device 22 may be different. In one embodiment, it can be locking coupled with close proximity to a mobile device that is exterior to the door.

In another embodiment of the present invention, the intelligent door lock system back-end 68 can track performance of doors and friction levels across time and build a simple service to encourage users to maintain their doors better, as discussed above.

This information can be stored in the one or more databases 64.

In one embodiment of the present invention, the intelligent door lock system 10 unlocks when a selected temperature is reached, when smoke is detected, when a fire is detected by processor 38 and the like. As non-limiting examples, the intelligent door lock system 10 unlocks the bolt/lock 24 when a temperature is sensed by the temperature sensor 46 that, as non-limiting examples, is greater than 40 degrees C., any temperature over 45 degrees C. and the like. The temperature sensor 46 212 sends a signal to the processor 36 which communicates with the motor 38 that will then cause the drive shaft 14 to rotate sufficiently and unlock the bolt/lock 24. An arm can also be activated. It will be appreciated that the processor 36 can be anywhere as long as it is in communication with the temperature sensor 46, and the motor 38, which can be at the intelligent door lock system 10, at the back-end 68, anywhere in the building, and at any remote location. The processor 36 determines if there is an unsafe condition, e.g., based on a rise in temperature and this then results in an unlocking of the bolt/lock 24.

In one embodiment, the intelligent door lock system back-end 68 can track performance of doors and friction levels across time and build a service to encourage users to better maintain their doors, as discussed above.

The front portion of the door 120 (that is outside relative to a building or dwelling) shown in FIG. 17 looks like a typical door 120 with a bolt assembly 122 and a doorknob and lock assembly 124. The back portion of the door 120, that is inside of the dwelling when the door 120 is closed, illustrated in FIG. 18(b) has the same doorknob and lock assembly 124, but then has an intelligent door lock system 100 that is retrofitted onto the bolt assembly 124 as described below in more detail.

The intelligent door look assembly 100 may have an extension gear which extends through the baseplate of the smart door lock. The baseplate may have one or more oval mounting holes to accommodate various rose screw distances from 18 mm to 32 mm to accommodate various different doors. In one implementation, the intelligent door lock system 100 may have a circular shape and also a rotating bezel. The rotating bezel allows a user to rotate the smart door lock and thus manually lock or unlock the bolt as before. The extension gear extends through the baseplate and then interacts with the existing bolt elements and allows the smart door lock to lock/unlocks the bolt. The extension gear may have a modular adapter slot at its end which interfaces with an extension rod of the bolt assembly 124. These modular adapters, as shown in FIG. 23(b), may be used to match the existing extension rod of the bolt assembly 124. The smart door lock housing may further include an energy source, such as a battery, a motor assembly, such as a compact, high-torque, high-accuracy stepper motor, and a circuit board that has at least a processor, a first wireless connectivity circuit and a second wireless connectivity circuit, as described above. In one embodiment, the first wireless connectivity circuit may be a Bluetooth chip that allows the smart door lock to communicate using a Bluetooth protocol with a computing device of a user, such as a smartphone, tablet computer and the like. The second wireless connectivity circuit may be a WiFi chip that allows the smart door lock to communicate using a WiFi protocol with a back-end server system. The circuit board components may be intercoupled to each other and also coupled to the energy source and the motor for power and to control the motor, respectively. Each of the components described here may be coupled to the energy source and powered by the energy source.

FIG. 19 illustrates the smart door lock system 100 being retrofitted onto a bolt in a door 10. As shown in FIG. 19, when the intelligent door lock system 100 is installed on the door 120, the thumb turn 124 is removed (replaced by the bezel that allows the user to manually unlock or lock the bolt.) In addition, the extension gear 126 of the intelligent door lock system 100, and more specifically the slotted portion 126(a) at the end of the extension gear, is mechanically coupled to the extension rod 128 of the bolt assembly as show in FIG. 19. When the intelligent door lock system 100 is installed, as shown in FIG. 19, the user can rotate the bezel 132 to manually lock or unlock the bolt assembly. In addition, when commanded to do so, the motor assembly in the intelligent door lock system 100 can also turn the extension gear 126 that in turn turns the extension rod and lock or unlock the bolt assembly. Thus, the extension gear 126 allows the smart door lock to act as a manual thumb turn (using the bezel) and rotate either clockwise or counterclockwise to engage or disengage the bolt of a bolt. The extension gear 126 is designed in a manner to control the physical rotation of extension rods/axial actuators/tail pieces/tongues 128 which are traditional rotated by means of a thumb turn. This is achieved by designing the extension gear 126 with modular gear adapters as shown in FIG. 23(b) to fit over the extension rod 22 as shown. This allows the extension gear 126 to fit with a variety of existing extension rods.

FIG. 20 illustrates a set of interactions between the intelligent door lock system 100, mobile or computing device 210 and intelligent door lock system back-end 68, that may include a pairing process 138 and a lock operation process 140. During the pairing process 138, the intelligent door lock system 100 and mobile or computing device 210 can be paired to each other and also authenticated by the intelligent door lock system back-end 68. Thus, as shown in FIG. 20, during the pairing process, the intelligent door look system 100 is powered on and becomes discoverable, while the mobile or computing device 210 communicates with the intelligent door lock system back-end 68, and has its credentials validated and authenticated. Once the mobile or computing device 210, and the app on the mobile or computing device 210, is authenticated, the mobile or computing device 210 discovers the lock, such as through a Bluetooth discovery process, since the intelligent door look system 100 and the mobile or computing device 210 are within a predetermined proximity to each other. The mobile or computing device 210 may then send a pairing code to the intelligent door look system 100, and in turn receive a pairing confirmation from the intelligent door lock system 100. The pairing process is then completed with the processes illustrated in FIG. 20. The lock operation may include the steps listed in FIG. 20 to operate the intelligent door look system 100 wirelessly using the mobile or computing device 210.

The intelligent door lock system 100 may be used for various functions. As a non-limiting example, the intelligent door lock system 100 may enable a method to exchange a security token between mobile or computing device 210 and the intelligent door look system 100. All or all of the intelligent door look systems 100 may be registered with the intelligent door lock back-end 68 with a unique registration ID. The unique ID of the an intelligent door look system 100 may be associated with a unique security token that can only be used to command a specific intelligent door look system 100 to lock or unlock. Through a virtual key provisioning interface of the intelligent door lock system back-end 68, a master user, who may be an administrator, can issue a new security token to a particular mobile or computing device 210. The intelligent door look system 100 can periodically broadcast an advertisement of its available services over System Networks. When the mobile or computing device 210 is within a predetermined proximity of the intelligent door look system 100, which varies depending on the protocol being used, the mobile or computing device 210 can detect the advertisement from the intelligent door lock assembly 100.

The application on the mobile or computing device 210 detects the intelligent door look system 100 and a communications session can be initiated. The token, illustrated as a key 118 in FIG. 20, is exchanged and the lock is triggered to unlock automatically. Alternatively, if the intelligent door look system 100 is equipped with a second wireless communications circuit, then the intelligent door look system 100 can periodically query the intelligent door lock system back-end 68 for commands. A user can issue commands via a web interface to the intelligent door lock system back-end 68, and the intelligent door look system 100 can lock or unlock the door 120. The intelligent door lock system 100 may also allow the user to disable auto-unlock, at which time the application on the user's mobile or computing device 210 can provide a notification which then allows the user to press a button on the mobile or computing device 210 to lock or unlock the lock.

The intelligent door lock system 100 may also allow for the triggering of multiple events upon connection to an intelligent door look system 100 by a mobile or computing device 210. As a non-limiting example, the intelligent door look system 100 can detect and authenticate the mobile or computing device 210, as described herein, and initiate a series of actions, including but not limiting to, unlocking doors 100, turning on lights, adjusting temperature, turning on stereo etc. The commands for these actions may be carried out by the mobile or computing device 210 or the intelligent door lock system back-end 68. In addition, through a web interface of the intelligent door lock system back-end 68, the user may define one or more events to be triggered upon proximity detection and authentication of the user's mobile or computing device 210 to the intelligent door look system 100.

The intelligent door lock system 100 may also allow for the intelligent triggering of events associated with an individual. In particular, environmental settings may be defined per individual in the intelligent door lock system back-end 68 and then applied intelligently by successive ingress by that person into a building that has an intelligent door look system 100. For example: person A arrives home and its mobile or computing device 210 is authenticated by the intelligent door look system 100. His identity is shared with the intelligent door lock system back-end 68. The intelligent door lock system back-end 68 may send environmental changes to other home controllers, such as “adjust heat to 68 degrees”. Person B arrives at the same building an hour later and her mobile or computing device 210 is also authenticated and shared with the intelligent door lock system back-end 68. The intelligent door lock system back-end 68 accesses her preferred environmental variables such as “adjust heat to 71 degrees”. The intelligent door lock system back-end understands that person B has asked for a temperature increase and issues the respective command to the dwelling thermostat. In one example, the intelligent door lock back-end system 68 has logic that defers to the higher temperature request or can deny it. Therefore if person A entered the home after person B, the temperature would not be decreased.

FIGS. 21(a)-(g) are examples of a user interface for an owner of a building that has an intelligent door lock system 100. These user interfaces may be seen by a user who is the owner of a building that has an intelligent door look system 100 with the unique ID. FIG. 21(a) is a basic home screen while FIG. 22(b) shows the smart door locks (in a keychain) which the user of the mobile or computing device 210 has access rights to in intelligent door lock system 100. FIG. 21(c) illustrates an example of a user interface when a particular intelligent door look system 100 is locked. FIG. 22(d) illustrates an example of a user interface when a particular intelligent door look system 100 is unlocked. FIGS. 21(e) and (f) are user interface examples that allow the owner to add other users/people to be able to control the intelligent door look system 100 of the building. FIG. 21(g) is an example of a configuration interface that allows the owner of the building to customize a set of permissions assigned for each intelligent door lock system 100.

FIGS. 22(a)-(e) are examples of a user interface for a guest of an owner of a building that has an intelligent door lock system 100.

FIGS. 23(a) and (b) illustrate an intelligent door look system 100 and extension gear adapters 142. In particular, FIG. 23(a) shows the bolt of a lock device with an empty extension gear receptacle that allows different extension gear adapters 150 (shown in FIG. 7B) to be inserted into the receptacle so that the an intelligent door look system 100 may be used with a number of different bolts of lock devices that each have a different shaped extension rod and/or extension rods that have different cross-sections.

Referring now to FIG. 24, 1212 is a block diagram illustrating embodiments of a mobile or computing device 210 that can be used with intelligent door lock system 10.

The mobile or computing device 210 can include a display 1214 that can be a touch sensitive display. The touch-sensitive display 1214 is sometimes called a “touch screen” for convenience, and may also be known as or called a touch-sensitive display system. The mobile or computing device 210 may include a memory 1216 (which may include one or more computer readable storage mediums), a memory controller 1218, one or more processing units (CPU's) 1220, a peripherals interface 1222, Network Systems circuitry 1224, including but not limited to RF circuitry, audio circuitry 1226, a speaker 1228, a microphone 1230, an input/output (I/O) subsystem 1232, other input or control devices 1234, and an external port 1236. The mobile or computing device 210 may include one or more optical sensors 1238. These components may communicate over one or more communication buses or signal lines 1240.

It should be appreciated that the mobile or computing device 210 is only one example of a portable multifunction mobile or computing device 210, and that the mobile or computing device 210 may have more or fewer components than shown, may combine two or more components, or a may have a different configuration or arrangement of the components. The various components shown in FIG. 24 may be implemented in hardware, software or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

Memory 1216 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 1216 by other components of the mobile or computing device 210, such as the CPU 1220 and the peripherals interface 1222, may be controlled by the memory controller 1218.

The peripherals interface 1222 couples the input and output peripherals of the device to the CPU 1220 and memory 1216. The one or more processors 1220 run or execute various software programs and/or sets of instructions stored in memory 1216 to perform various functions for the mobile or computing device 210 and to process data.

In some embodiments, the peripherals interface 1222, the CPU 1220, and the memory controller 1218 may be implemented on a single chip, such as a chip 1242. In some other embodiments, they may be implemented on separate chips.

The Network System circuitry 1244 receives and sends signals, including but not limited to RF, also called electromagnetic signals. The Network System circuitry 1244 converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. The Network Systems circuitry 1244 may include well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. The Network Systems circuitry 1244 may communicate with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication.

The wireless communication may use any of a plurality of communications standards, protocols and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), BLUETOOTH®, Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for email (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), and/or Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS)), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document.

The audio circuitry 1226, the speaker 1228, and the microphone 1230 provide an audio interface between a user and the mobile or computing device 210. The audio circuitry 1226 receives audio data from the peripherals interface 1222, converts the audio data to an electrical signal, and transmits the electrical signal to the speaker 1228. The speaker 1228 converts the electrical signal to human-audible sound waves. The audio circuitry 1226 also receives electrical signals converted by the microphone 1230 from sound waves. The audio circuitry 1226 converts the electrical signal to audio data and transmits the audio data to the peripherals interface 1222 for processing. Audio data may be retrieved from and/or transmitted to memory 1216 and/or the Network Systems circuitry 1244 by the peripherals interface 1222. In some embodiments, the audio circuitry 1226 also includes a headset jack. The headset jack provides an interface between the audio circuitry 1226 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

The I/O subsystem 1232 couples input/output peripherals on the mobile or computing device 210, such as the touch screen 1214 and other input/control devices 1234, to the peripherals interface 1222. The I/O subsystem 1232 may include a display controller 1246 and one or more input controllers 210 for other input or control devices. The one or more input controllers 1 receive/send electrical signals from/to other input or control devices 1234. The other input/control devices 1234 may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, and joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 1252 may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons may include an up/down button for volume control of the speaker 1228 and/or the microphone 1230. The one or more buttons may include a push button. A quick press of the push button may disengage a lock of the touch screen 1214 or begin a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, which is hereby incorporated by reference in its entirety. A longer press of the push button may turn power to the mobile or computing device 210 on or off. The user may be able to customize a functionality of one or more of the buttons. The touch screen 1214 is used to implement virtual or soft buttons and one or more soft keyboards.

The touch-sensitive touch screen 1214 provides an input interface and an output interface between the device and a user. The display controller 1246 receives and/or sends electrical signals from/to the touch screen 1214. The touch screen 1214 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects, further details of which are described below.

A touch screen 1214 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. The touch screen 1214 and the display controller 1246 (along with any associated modules and/or sets of instructions in memory 1216) detect contact (and any movement or breaking of the contact) on the touch screen 1214 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on the touch screen. In an exemplary embodiment, a point of contact between a touch screen 1214 and the user corresponds to a finger of the user.

The touch screen 1214 may use LCD (liquid crystal display) technology, or LPD (light emitting polymer display) technology, although other display technologies may be used in other embodiments. The touch screen 1214 and the display controller 1246 may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with a touch screen 1214.

A touch-sensitive display in some embodiments of the touch screen 1214 may be analogous to the multi-touch sensitive tablets described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in their entirety. However, a touch screen 1214 displays visual output from the portable mobile or computing device 210, whereas touch sensitive tablets do not provide visual output.

A touch-sensitive display in some embodiments of the touch screen 1214 may be as described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 12, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser. No. 11/038,590, “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed Jan. 18, 2005; (6) U.S. patent application Ser. No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety.

The touch screen 1214 may have a resolution in excess of 1000 dpi. In an exemplary embodiment, the touch screen has a resolution of approximately 1060 dpi. The user may make contact with the touch screen 1214 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which are much less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, the mobile or computing device 210 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from the touch screen 1214 or an extension of the touch-sensitive surface formed by the touch screen.

In some embodiments, the mobile or computing device 210 may include a physical or virtual click wheel as an input control device 1234. A user may navigate among and interact with one or more graphical objects (henceforth referred to as icons) displayed in the touch screen 1214 by rotating the click wheel or by moving a point of contact with the click wheel (e.g., where the amount of movement of the point of contact is measured by its angular displacement with respect to a center point of the click wheel). The click wheel may also be used to select one or more of the displayed icons. For example, the user may press down on at least a portion of the click wheel or an associated button. User commands and navigation commands provided by the user via the click wheel may be processed by an input controller 1252 as well as one or more of the modules and/or sets of instructions in memory 1216. For a virtual click wheel, the click wheel and click wheel controller may be part of the touch screen 1214 and the display controller 1246, respectively. For a virtual click wheel, the click wheel may be either an opaque or semitransparent object that appears and disappears on the touch screen display in response to user interaction with the device. In some embodiments, a virtual click wheel is displayed on the touch screen of a portable multifunction device and operated by user contact with the touch screen.

The mobile or computing device 210 also includes a power system 1214 for powering the various components. The power system 1214 may include a power management system, one or more power sources (e.g., battery 1254, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

The mobile or computing device 210 may also include one or more sensors 1238, including not limited to optical sensors 1238. An optical sensor can be coupled to an optical sensor controller 1248 in I/O subsystem 1232. The optical sensor 1238 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. The optical sensor 1238 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with an imaging module 1258 (also called a camera module); the optical sensor 1238 may capture still images or video. In some embodiments, an optical sensor is located on the back of the mobile or computing device 210, opposite the touch screen display 1214 on the front of the device, so that the touch screen display may be used as a viewfinder for either still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of the optical sensor 1238 can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor 1238 may be used along with the touch screen display for both video conferencing and still and/or video image acquisition.

The mobile or computing device 210 may also include one or more proximity sensors 1250. In one embodiment, the proximity sensor 1250 is coupled to the peripherals interface 1222. Alternately, the proximity sensor 1250 may be coupled to an input controller in the I/O subsystem 1232. The proximity sensor 1250 may perform as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device,” filed Sep. 30, 2005; Ser. No. 11/240,788, “Proximity Detector In Handheld Device,” filed Sep. 30, 2005; Ser. No. 13/096,386, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices,” filed Oct. 24, 2006; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables the touch screen 1214 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call). In some embodiments, the proximity sensor keeps the screen off when the device is in the user's pocket, purse, or other dark area to prevent unnecessary battery drainage when the device is a locked state.

In some embodiments, the software components stored in memory 1216 may include an operating system 1260, a communication module (or set of instructions) 1262, a contact/motion module (or set of instructions) 1264, a graphics module (or set of instructions) 1268, a text input module (or set of instructions) 1270, a Global Positioning System (GPS) module (or set of instructions) 1272, and applications (or set of instructions) 1272.

The operating system 1260 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

The communication module 1262 facilitates communication with other devices over one or more external ports 1274 and also includes various software components for handling data received by the Network Systems circuitry 1244 and/or the external port 1274. The external port 1274 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple Computer, Inc.) devices.

The contact/motion module 106 may detect contact with the touch screen 1214 (in conjunction with the display controller 1246) and other touch sensitive devices (e.g., a touchpad or physical click wheel). The contact/motion module 106 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred, determining if there is movement of the contact and tracking the movement across the touch screen 1214, and determining if the contact has been broken (i.e., if the contact has ceased). Determining movement of the point of contact may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, the contact/motion module 106 and the display controller 1246 also detects contact on a touchpad. In some embodiments, the contact/motion module 1284 and the controller 1286 detects contact on a click wheel.

Examples of other applications that may be stored in memory 1216 include other word processing applications, JAVA-enabled applications, encryption, digital rights management, voice recognition, and voice replication.

In conjunction with touch screen 1214, display controller 1246, contact module 1276, graphics module 1278, and text input module 1280, a contacts module 1282 may be used to manage an address book or contact list, including: adding name(s) to the address book; deleting name(s) from the address book; associating telephone number(s), e-mail address(es), physical address(es) or other information with a name; associating an image with a name; categorizing and sorting names; providing telephone numbers or e-mail addresses to initiate and/or facilitate communications by telephone, video conference, e-mail, or IM; and so forth.
